As the Nile was held sacred by the Egyptians, as well as the animals it contained, to which they annually sacrificed a girl, or as others say, both a boy and girl, God might have designed this plague as a punishment for such idolatry and cruelty; and to shew them the baseness of those elements which they reverenced, and the insufficiency of the gods in which they trusted. All the punishments brought upon them bore a strict analogy to their crimes.
Exodus 10:1
hardened <03513> [I have hardened.]
display <07896> [that I.]
Exodus 12:30
great cry <01419 06818> [and there was a great cry.]
No people were more remarkable and frantic in their mournings than the Egyptians. When a relative died, every one left the house, and the women, with their hair loose, and their bosoms bare, ran wild about the street. The men also, with their apparel equally disordered, kept them company; all shrieking, howling, and beating themselves. What a scene of horror and distress must now have presented itself, when there was not a family in Egypt where there was not one dead!
